Slow recovery of High Arctic heath communities from nitrogen enrichment

Acknowledgements We are indebted to Ian Alexander who initiated the fertilisation experiment with SJW; to successive researchers involved in the experiment, John Baddeley, Nanette Madan, Lars Hogbom, Bernard Moyersen, Carmen Gordon; and to field assistants, Alison Horsburgh, Andrew Coughlan, Jo Wynn, Lora Crabtree. We thank Hans Kruijer and Michael Stech for assistance with bryophyte species identification in 2011. Funding for the initial experiment was provided by the NERC Arctic Terrestrial Ecology Special Topic Programme (GR3/9424, GR9/3433) with additional support from the CEC TMR Programme, Ny-Ålesund LSF and the British Ecological Society. This recovery study was funded by NERC (NE/I016899/1). The research was made possible by use of NERC facilities at Harland Huset; special thanks to Nick Cox and colleagues for their unfailing hospitality and support.Peer reviewedPostprintPostprin

Waterfowl and human disturbace

The movement of people in the countryside has considerably changed in recent decades. A man occurs in places where he previously didn't and do things that previously couldn't do. It is for example about the rapid growth of ecotourism and various kinds of sports, from water sports to sports hunting or increased traffic. Waterbirds are for their size and way of life easy target for finders of binoculars and cameras. Effect of these on numbers, distribution and behaviour of waterbirds, it is not in the interest of mentioned people. Education, training and implementation of various conservation or restrictive measures, is often the only way how to protect the birds from negative human impact. Currently there are many researches focusing on the impact of different types of human disturbance. There arise any recommendations how to reduce the impact of these activities. Examples of different types of disturbance and its effect on water birds as well as its effect on animals during recurring activities are summarized in this study
